Not able to connect to fabric using RESTful API server on step 3

Hi,

I was able to deploy chaincode successfully and also able to query using peer but getting error while executing query from rest client

[
  Error: 14 UNAVAILABLE: failed to connect to all addresses
 {
    code: 14,
    metadata: Metadata { _internal_repr: {}, flags: 0 },
    details: 'failed to connect to all addresses'
  }
]

I checked my firewall, all ports are accessible and I'm able to telnet Peer endpoint
